ANDREW C. ZENORINI, OF WEST HOIBOKEN, NEW JERSEY.

NEEDLE MECHANISM FOR EMBROIDERY-MACHINES.

Specification of Letters Patent.

Application led December 31, 1914. Serial No. 879,968.

To aZ w/wm t may concern Be it known that I, ANDREW C. ZENORINI, a subject of the King of Italy, and a resident of West Hoboken, in the county of Hudson and State' of New Jersey, have invented certain new and useful Improvements in Needle Mechanism for Embroidery-Machines, of which the following is a specification.

This invention relates to improvements in needle mechanism for embroidery machines.

By the use of my invention I am enabled with great rapidity to produce embroidery designs in a plurality of colors with uniformity of color in relation to the design to be produced and without the rethreading of needles as was heretofore possible; I may have in one design and operating through the agency of one shuttle or shuttle hole any desirable number of needles each threaded with a different shade or color of thread and I may change from one color or shade to another almost instantly and without the usual rethreading of needles, resulting in the saving of the time and labor of the operator and permitting a vastly greater amount of colored design work to be accomplished by a single machine than has heretofore been possible.

Another feature of my invention consists in the provision of' means enabling the operator to throw into operative position almost instantly and by simple operations one series of needles and to lock the same into such operative position, .and with the same means and with equal speed the operator is enabled to throw out of operation another series of needles, and the needles so thrown out of operation may also be locked in inoperative position.

Another feature of my invention consists in the mounting of needles in a series of independently movable needle carriers each movable freely forwardly into operative position and rearwardly out of operative position without the use of springs or the like; means for moving a series of said needles simultaneously into or out of operative posi-V tion; means for simultaneously locking a complete series in operative position and means for simultaneously shifting the series of needles actuated into operative position laterally into alinement with the shuttle hole of the machine and means for independently locking the series of reserved needles in inoperative position'.

In the accompanying drawings in which similar reference characters designate cor@ responding parts throughout the several views, Figure l is a plan view of a portion of needle mechanism embodying my invention, the carrier shifting mechanism being omitted; Fig. 2 isa view taken on the line 2-2 of Fig. l showing one end of the needle bar; Fig. 3 is a section on the line 3 3 of Fig. l, the shuttle and guides being omitted; Fig. 4 is a front elevation at one end of my needle mechanism showing my preferred mechanism for locking the needle carriers in either operative or inoperative position; Fig. 5 is a view in plan of the reverse side of my improved needle mechanism; Fig. 6 is a side elevation of one end of my improved needle mechanism, showing my 1 preferred means for shifting carriers out of and into operative position, and also for moving the same laterally into alinement with the shuttle holes; Fig. 7 is an end elevation of the devices shown in Fig. 6; Fig. 8 is a side elevation partly in section, viewed from the side opposite to that of Fig. 6; and Fig. 9 is a section on the line 9-9 of Fig. 8; Fig.

l0 is a section of needle mechanism andV needle plate with the operating parts of the needler mechanism; and Fig. 11 is an end elevation showing my movement limiting plate for the carriers provided with thread slots, and also showing the parts contiguous to said plate. A

Referring now to these drawings, F indicates the needles of an embroidery machine mechanism each of which is suitably mounted in a needle carrier A by means of a pressureclip B to which pressure is ap- Iatented Oct. 31, 1916.

plied by means of a screw b. Each of the i needle carriers A is independently mounted to slide freely and without spring pressure or the like rearwardly andV forwardly in slideways D formed on a laterally movable shift bar H and intermediate guide bars D2, said carriers being retained within such slideways by retaining strips VD'secured to thev guide bars by screws d or in any other suitable manner. The guide bars D2 may be welded or otherwise secured to the shift barhH or may be formed integrally therewit The shift barI-I is mounted to have lateral or side wise movement on a relatively stationary supporting or bed plate G which is preferably channeled or grooved on its upper surface to form a rib g at one edge and said supporting plate is connected by bolts g to a reciprocating bracket G which is mounted on a rod G2 suitably secured to the frame, and said bracket is pivotally connected by link g2 to one arin of an angulairocking lever g3, which is pivoted on a shaft g4 and has its other arm pivotally connected to a vertical rod g5 provided at its lower end with a roller g@ ruiming iii a groove e in a cam wheel Z which is rotated by a shaft Zfrom any suitable source of power. The cam groove e is such that it imparts to the reciprocating bracket an initial movementn of the needle through the shuttle hole, then a slight backward movement to loop the thread of the needle so as to permit the passage of the shuttle therethrough, and a final movement through such holel and back again to complete a stitch.

Suitable means for moving the needle carriers rearwardly and forwardly in their slideways is preferably provided so that one series of needles may be moved into operative position, as shown in Fig. l, and another series of needlesmay be moved into reserved'position as shown inY said figure, and for this purpose I preferably provide each of such independently movable carriers with al vertically projecting pin C secured inthe carrier by a screw threaded at the lower end c thereof; or in any other suitable manner, and I furthermore preferably provide means for engaging and moving rearwardly or forwardly as may be desired a series of such vertically projecting pins. My preferred means for engaging the pins and moving the needle carriers consists of a removably mounted and laterally shiftable carrier-shifting shaft comprising acylindr'i'ca'l rod Q. rocked by means of a lever V (see Figs. i to 9) which is mounted. in suitable bearings R and extends longitudinal-ly over'the needle carriers. Suitably keyed to said bar by means of screws s or in any other suitable way are a pluralityvof what I shall term hammers S which. are suitably spaced on the bar to engage and move into or out of operative position as Vdesired a series of needle carriers. I prefferably' provide a plurality ofl such bars each provided with a series of hammers in suitably spaced relations so that I may readily and quickly engage and move either `every alternate needle out of engagement as shown in Fig. l, in which is illustrated what is commonly called a Yfour-quarter machine, or I may move every third needle into operative position in what isrcominonly called a six-quarter machine, or I may move every fourth needle into operative position in what is called an eight-quarter machine and so on, the other needles which may consist of one or more series threaded in dii'erent colors being, of COurse, moved rearwardly out of operative position. The said. shaft Q.

Vof rocking links K pivoted at one end inA blocks or projections Gr on the. supportingl or bed plate G and. pivoted at thev other` iin operating. lever J end to the strip E. l for rocking the links K' is provided: at the end of the machine. lever is moved from the position shown in full lines to the dotted line position (Fig.

4) the strip E Vwill be moved downwardly and out of locking engagement with the needle carriers or slides, whereupon. the saine may be moved, and upon the movement of the lever in the opposite. direction, the links will be rocked andthe Vedge-of the strip E will enter the grooves I of ysuch of the carriers A.. as are-in operative. position, thus securely locking suoli needle carriersfin such position. Suitable means is also preferably employed forlocking the. reserved needles in inoperative position and I pref.-

erably employ a locking strip disposedV along the rear edge of the shift bar mountedy and operated 1n all respects similar tothe locking VStrip E hereinabove described.

Obviouslyv when the.V

My preferred means `for Vshifting and ,Y guiding the shift-bar II Vlaterally to bring.

the desired series ofneedles into properV aliiiement with therneedle plate holes-Y; consists in providing suitable guide slots U .along its length and inserting through Such.y

slots suitable guide pins preferably provided with bolt heads T, (see Fig. 5). The.'

said. shift-bar is preferably moved laterallyin the supporting plate G at suitable places,

by means of a screw shaft N secured at` one end to said. shift-bar II in any suitable manner such as by the plate-n and screw n', the said screw shaft N being threaded in a nuty I mounted in a bearing bracket M suitably secured to the supporting plate G by screws g2 or in any other suitable manner.

Obvi- Y ously when the nut P isrotated in one directiony the screw shaft N Ywill. cause the plate H to be pushed in one direction and` when the screw P is rotated in the oppositeV direction it will cause the plate I-I toY be pulled in the opposite direction.

ment thereof.

It will be seen. from the above that I have provided a device in which the needles are mounted uponV independently movable needle' carriers or slides and that such needles may be threaded, one series in one color, and another series in anothercolor, and that the series of needles may be changed as desired from each alternate needle to each third needle and so on, thus enabling the threading of any desired series with any suitable color and enabling the throwing into action of a *ries of needles threaded in one color while one or more series of needles threaded in one or more colors may be thrown out of action or held in reserve and any suitable number of needles may be used or operated with the same shuttle and the same needle plate hole by simply shifting the shiftV bar into proper position. Furthermore, I am enabled with great rapidity by my removable rod Q, to shift one series of needle carriers into position and other series out of position, all the series of needles being threaded in suitable colors.

In the preferred form of needle mechanism shown, I preferably provide double the number of needles that may cooperate at one time with the shuttle holes of the most closely positioned machine at present in use, viz.` the four-quarter machine.

Suitable means for limiting the forward or rearward movement of the needle carriers is provided and as shown the forward movement is limited by means of a projection L which is adapted to abut against a cut out portion in the shift bar I-I while the movement rearwardly is limited by the vertical pins C engaging a plate, X disposed along the rear edge of the plate H and secured by suitable screws on the bars D, and this strip X if desired may be provided with guide apertures X (Fig. 11) for the thread.
